Divide the oscillator by 10^7 to generate a 1 pulse per second output. You might be able to tell your frequency counter to measure with a 1 second gate time and take out a gate signal, if the counter provides it (or add your own). Compare the phase of this to WWV by recording both with a PC sound card for 24 hours. Adjust it until it holds 1/10 of second per day which is 1 ppm.
